语言形式上，我有点在意。
我就是有一个臭毛病，看见冗余词汇就浑身激灵一下。
当一个语言form上不好的冗余词汇，被无数人来回来去的用的时候，我就激灵来，激灵
去，觉得浑身痒痒。。。
比如说，华人上很多人经常说的＂真心觉得＊＊不好看＂
或者是＂真心觉得＂后面加一句比较难听的话。
我一看就浑身痒（是真的physically 痒）。
因为＂觉得＊＊难看＂还需要加上＂真心＂吗？那肯定是真心的啊！！。。你都有勇气
说出来了，没人怀疑你不真心啊。
＂不刻意节食＂也是。就说＂不节食＂就行了。刻意两个字完全是冗余。
总之，对没有信息量的词汇，反复被使用，我有一种想划横线把其删除的强迫症。。。

下文是由曾为中文网撰稿的留学生曹起曈提供的样稿。曹起曈毕业于南京外国语学校，

所谓比较，就是辨析其相似和不同之处。对于“苹果”(apple)和“橙”(orange)而言

Syllepsis is a particular type of zeugma in which the clauses are not

婴儿并不是definitively知道，什么是猫，什么是狗，什么叫“五颜六色”，什么叫“

成人，在学习的时候，是algebric learning。主语，谓语，宾语，你知道一个公式然

"谒"不是一个平常的词，含义不说，起码有强调的作用，然而后面紧接的“暴雪、奇瑰

practically this is very useful, for example,
1. final boolean FLAG=true;
2. if(FLAG)... else...;
you can change line 1, to be false, or to be non-const,

You can think in that way. After all, super class's private variables will

But semantic visibility control is really the job of compiler. If you got
that wrong, the compiler wouldn't let you go. Also you might want to know
that semantic visibility is controlled at class level not at object level. |

for case 1 when the reference is returned, it is made into

for all POD and user defined types, there must be a copy constructor
which takes a reference type and return (not really return, but contruction)
a object of that type. which is then returned to the caller.
so ur case 1 fn semantic is: (assuming do something instead of do nothing

楼主给出的 foldLeft 写法，和普通用循环的写法并无很大的分别，都是描述的计算
powerset 过程。而上述用 filterM 的写法，直接对应的是 powerset 的数学定义。
这两种表达方式的差别，正是 operational semantics 和 denotational semantics
的差别。通常，denotational 的抽象程度要高一些，但从另一个角度看，operational
可以更细致地区分语义上的差别。所以，取决于使用的上下文，并不能笼统地说一种
就一定好于另一种。
但是从语言设计的角度出发，即能够允许 operational 也能够允许 denotational 方
式定义函数或者描述事件的程序语言，要比只能允许其中一种方式的语言要更加
expressive。
的确，多数情况下我们并不关心 powerset 是如何实现的，有现成的库函数调用就好了
。但是不深入学习，就会错过一次锻炼抽象能力的机会。而正确恰当的抽象能力，才是
一个 architect 和一个 engineer 的真正区别。

(1) std :: unique_ptr < T > (C++11) does not require T to implement copy
semantics.
http://en.cppreference.com/w/cpp/memory/unique_ptr
(2) range declaration type ... my personal advice is this.
for ( Pack & iter : pack_map_ ) { ... }
Pay attention that I specify the reference (ampersand), which avoids the
copy semantics issue.
This is actually a quite common problem. C++ programmers I know forgot that
without taking the reference (ampersand), the range-based for in C++11 will
make copies. Thus,... 阅读全帖 |

IRS有个PFIC-compliant report的规定，简单说，针对美国纳税居民申报持有外国基金
的税务处理,对应的FORM 8621。因为跨境居住的美加居民比较多，所以这个问题还是比
较常见的。
我当然可以把目前的规则HARD CODING到代码里。
但是，关于加拿大的RESP账户，一直存在争议。如果IRS改变主意了，承认RESP和RRSP
具有同样地位，RESP不再属于PFIC了，软件该怎么办呢？
我当然可以打开EMACS，一行一行改代码。
然后，IRS又改变注意了，承认加拿大的TFSA也具有同样地位。
然后，IRS又承认欧洲的某个国家的基金不是PFIC了（因为其主要投资于美国）。
然后，IRS又承认百慕大的某个基金不是PFIC了。
然后。。。。。
可是我不想这么做，不想把每年的软件更新变成一项体力劳动。
所以，我想把税法的具体规则抽象出来，用一种类似简单英语的表示方法，存在JSON里。
每年开春，我就根据IRS的新规则，更新一下这个JSON文本，然后软件会对其做
semantics parsing，产生新的运算规则，并生成新的版本。
我发帖的目的，就是... 阅读全帖 |
